Timber vs Steel Frames | Bushfire Performance & Environmental Impact
Timber or Steel-
Which can withstand the heat?
Timber frames are a superior choice to steel frames in bushfire-prone areas due to their predictable fire performance and natural insulating properties. Unlike steel, which can rapidly lose strength and distort under extreme heat, structural timber chars at a controlled rate, forming a protective layer that helps maintain structural integrity for longer. This predictable behaviour allows timber framing to be engineered to meet Australian Bushfire Attack Level (BAL) requirements while delivering strong thermal performance, reduced heat transfer, and improved energy efficiency. For homeowners and builders seeking durable, bushfire-resilient construction, timber framing offers strength, safety, and long-term reliability.

HOW TIMBER CONSTRUCTION FIGHTS CLIMATE CHANGE
As the construction industry searches for smarter, greener solutions, timber frame construction is rapidly gaining attention. Beyond its timeless beauty and structural strength, timber framing plays a powerful role in carbon sequestration- helping to lock carbon into buildings for 100+ years! Wood is the only major structural material that is renewable and carbon-storing at the same time. If you're exploring sustainable building methods, eco-friendly homes, or low-carbon construction, a well-designed timber frame home can significantly reduce lifetime operational carbon emissions.
- Trees Absorb Carbon Naturally
- Wood Stores Carbon for Decades
- Buildings Become Carbon Storage Units
- Reduced thermal bridging
- Airtight building envelopes
- Lower heating and cooling costs
